Applications

Naive RAG (Retrieve-Read)

Simplest paradigm with indexing, retrieval, and generation.

Easy to implement, computationally efficient.

Limited control over retrieved information, LLM might struggle with synthesis.

Simple question answering, short document summarization.

Advanced RAG (Retrieve-Read-Rewrite-Rerank)

Builds on Naive RAG with pre-retrieval and post-retrieval processing for improved retrieval quality.

More control over information, improved response relevance.

More complex to implement than Naive RAG.

Complex question answering, longer document summarization.

Modular RAG (Flexible Architecture)

Most versatile paradigm with specialized modules for enhanced retrieval and processing

Highly customizable, allows for experimentation and innovation.

Most complex to implement, requires deeper understanding of individual RAG components.

Domain-specific question answering, tailored creative text generation tasks.
